Lieutenant Drummond Keith was a man about whom conversation always burst like a thunderstorm the moment he left the room. This arose from many separate touches about him. He was a light, loose person, who wore light, loose clothes, generally white, as if he were in the tropics; he was lean and graceful, like a panther, and he had restless black eyes.

He was very impecunious. He had one of the habits of the poor, in a degree so exaggerated as immeasurably to eclipse the most miserable of the unemployed; I mean the habit of continual change of lodgings. There are inland tracts of London where, in the very heart of artificial civilization, humanity has almost become nomadic once more. But in that restless interior there was no ragged tramp so restless as the elegant officer in the loose white clothes. He had shot a great many things in his time, to judge from his conversation, from partridges to elephants, but his slangier acquaintances were of opinion that “the moon” had been not unfrequently amid the victims of his victorious rifle. The phrase is a fine one, and suggests a mystic, elvish, nocturnal hunting.

He carried from house to house and from parish to parish a kit which consisted practically of five articles. Two odd-looking, large-bladed spears, tied together, the weapons, I suppose, of some savage tribe, a green umbrella, a huge and tattered copy of the Pickwick Papers, a big game rifle, and a large sealed jar of some unholy Oriental wine. These always went into every new lodging, even for one night; and they went in quite undisguised, tied up in wisps of string or straw, to the delight of the poetic gutter boys in the little grey streets.

I had forgotten to mention that he always carried also his old regimental sword. But this raised another odd question about him. Slim and active as he was, he was no longer very young. His hair, indeed, was quite grey, though his rather wild almost Italian moustache retained its blackness, and his face was careworn under its almost Italian gaiety. To find a middle-aged man who has left the Army at the primitive rank of lieutenant is unusual and not necessarily encouraging. With the more cautious and solid this fact, like his endless flitting, did the mysterious gentleman no good.

Lastly, he was a man who told the kind of adventures which win a man admiration, but not respect. They came out of queer places, where a good man would scarcely find himself, out of opium dens and gambling hells; they had the heat of the thieves’ kitchens or smelled of a strange smoke from cannibal incantations. These are the kind of stories which discredit a person almost equally whether they are believed or no. If Keith’s tales were false he was a liar; if they were true he had had, at any rate, every opportunity of being a scamp.

He had just left the room in which I sat with Basil Grant and his brother Rupert, the voluble amateur detective. And as I say was invariably the case, we were all talking about him. Rupert Grant was a clever young fellow, but he had that tendency which youth and cleverness, when sharply combined, so often produce, a somewhat extravagant scepticism. He saw doubt and guilt everywhere, and it was meat and drink to him. I had often got irritated with this boyish incredulity of his, but on this particular occasion I am bound to say that I thought him so obviously right that I was astounded at Basil’s opposing him, however banteringly.

I could swallow a good deal, being naturally of a simple turn, but I could not swallow Lieutenant Keith’s autobiography.

“You don’t seriously mean, Basil,” I said, “that you think that that fellow really did go as a stowaway with Nansen and pretend to be the Mad Mullah and–“
